How should you position an adult who is choking but becomes unresponsive?

When an adult who is choking becomes unresponsive, the appropriate action is to carefully lower them to the ground and begin CPR. This is crucial because an unresponsive individual cannot perform any voluntary actions, including coughing or breathing effectively. By lowering them to the ground, you ensure that they are in a safe and flat position, allowing for effective CPR.

Initiating CPR includes chest compressions that can help to dislodge an obstruction in the airway while also providing artificial circulation. During CPR, it is also important to check the airway for any visible obstructions after each set of compressions. If an obstruction is noted, techniques such as a finger sweep may be employed, but only if it is safe to do so.

Positions like sitting or remaining upright are not appropriate in this scenario because they do not allow for effective airway management or circulation. Performing abdominal thrusts on an unresponsive person is also dangerous as it might cause further complications, such as injury or additional choking. Thus, beginning CPR in a careful manner is imperative for the best chance of survival in a choking emergency.
